The present invention relates to attaching devices for electric wiresand has for its princlpal object to provide an article of this characterfor quickly, easily and effectively supporting the wire in apredetermined position. A further object is to provide an article ofthis character of a simple and practical construction, which is neat andattractive in appearance, strong and durable, relatively inexpensive tomanufacture and install in operative position and otherwise well adaptedfor the purposes for which the same is intended. Other objects andadvantages reside in the special construction, combination and ar- 1rangement of the various elements forming the invention as more fullyhereinafter described and claimed, reference being had to theaccompanying drawing forming part hereof, wherein like numerals refer tolike parts throughout the specification and in which Fi ure 1 is a sideelevational view showing the parts in assembled position,

Figure 2 is a transverse vertical sectional view through the basemember,

Figure 6 is a side elevational view of the base illustrating a differentmanner of attaching the same.

Referring now to the drawing in detail, the invention comprises a wireattaching or supporting terminal composed of a base member 5 preferablyof a circular formation and having a threaded opening 6 concentricallyarranged therein for receiving a screw 7 whereby to attach the baseto astationary object or fixture 8. The base has a pair of upstanding lugs 9formed at its opposite sides and at the edges of the base with the inneredge of the lugs of an arcuatev formation as clearly shown in Figure 8and an inwardly extending flange 10 formed at the upper inner edge ofeach of said lugs. The inner edge of the flanges is also curved. Aboutthe opening 6 upon the upper face of the base 5 is an annularcountersink 11 and communlcat- 1928. Serial No. 281,085.

ing with each side of which and disposed between the lugs 9 is a groove12 extending oppositely from the countersink to the opposite edges ofthe base. A circuit wire 13 is adapted to seat within the groove 12 andmay also be curved about the screw 7 in the countersink l1 and when usedas a terminal a second wire may have its end seated in the o positegroove 12 and also arranged in the countersink 11 to form a connectionwith the first named wire. A retaining member 14 is fitted upon the base5 having a body'portion provided with a central opening 15 for fittingover the screw 7 and of a diameter substantially larger than the screwto permit the free insertion tliereover, the lower edge of the bodyhaving an arcuate flange 16 formed at' the opposite sides thereof andadapted to engage the under side of the flanges 10 of the base upon theturning of the body thereon. The underside of the re-- taining member isprovided with a plurality of relatively short spikes 17 providingantislipping means between the bottom of the retaining member 14 and thewire seated in the countersink 11 so as to prevent accidental turningmovement of the retaining member and thus prevent disengagement of theparts.

Also at each end of the flanges 10 is provided a downwardly extendingprojection 18 adapted to engage the ends of the flanges 16 and preventrelative turning movement between the base 5 and the retaining member14' after the parts have been assembled in position. It will be apparentthat when it is, desired to remove the retaining member the prongs 17may be imbedded in the wire sufficiently to enable the pressing of there-' taining member inwardly to release the flanges 16 thereof from theprojections 18. The device constructed in accordance with the foregoingwill be found admirably adapted for connecting the ends of circuit wiresor for supporting the wire in a predetermined position upon a wall orother object. It is obvious from the foregoing that the inventionissusceptible of'various changes and modifications without departingfrom the spirit thereof or the scope of the appended claims, and Iaccordingly claim as my own all such forms of the invention to which Iam entitled.

I claim 1. An article of the class described comprising a fixedlymounted base having an 5 annular countersink formed in its upper surfacewith a groove extending outwardly at opposite sides thereof, a pair ofupstanding oppositely disposed lugs formed on the base with the groovesarranged therebetween,

a flange formed at the upper inner edge of each of said lugs, saidcountersink and grooves being adapted to receive a pair of wiresextending inwardly from opposite sides of the base, a post extendingupwardly from the base and a retaining member arranged upon the base andhaving a central opening for freely receiving the post and saidretaining member also having flanges formed at the opposite sidesthereof adapted for ena gaging the flanges of said lugs whereby tosecure the member upon the base.

2. An article of the class described comprising an attaching base havinga central threaded opening, an attaching screw inserted in said opening,a countersink formed in the upper surface of the base about saidopening, a groove extending from opposite sides of said countersink,said grooves and countersink being adapted to receive a pair of wiresextending inwardly from opposite sides of the base with their ends bentabout said screw, a pair of upstanding lugs formed at opposite sides ofthe base with the grooves disposed therebetween, a flange formed at :5the inner upper edge of each of said lugs, a

retaining member mounted on the base having flange segments formed atopposite sides thereof and adapted upon the turning of the retainingmember to ride under the flanges of said lugs, projections formed at theends of the flanges of said lugs forming stops for the ends of theflange segments of the retaining member and a plurality of downwardlyextending spikes formed at the under side of the retaining member anddisposed in gripping engagement with said wire.

3. A device of the class described comprising a base having an annularcountersink formed in its upper surface with a pair of grooves extendingradially from opposite sides thereof, retaining means for the baseextending upwardly at the center of the countersink, a pair of arcuateupstanding lugs formed on the base at opposite sides of 5 said grooves,said grooves being adapted for receiving a strand of wire and a wireretaining member revolubly mounted on said retaining means and movablelongitudinally thereof, and cooperating means carried by the lugs andthe wire retaining member for securing said member to the base.

In testimony whereof I aflix my signature.

PAUL SANGALS.
